KNOXVILLE - The daughter of former Alaska Gov. Sarah Palin told jurors this afternoon she was barraged by calls and texts after her number wound up on the Internet in 2008 courtesy of someone illegally accessing her mom's e-mail account.

"I got a few anonymous phone calls," Bristol Palin testified. "I checked my caller ID. It said an unknown number. When the phone calls kept coming through the night, it got more suspicious - different tones of voice, different area codes."

Bristol Palin's cell phone number was included in a screenshot of Sarah Palin's inbox that wound up on the Internet and, later, broadcast news networks.

Bristol Palin said her phone was essentially under siege for a week before she turned it over to the U.S. Secret Service.

After today's testimony ended, a journalist asked David C. Kernell, the former University of Tennessee student accused of masterminding the e-mail snafu, what he thought of Bristol Palin.

"Not my type," the 22-year-old Memphis defendant replied as he left the federal courthouse downtown.

Also this afternoon, a former state of Alaska employee testified he warned Sarah Palin's husband to get rid of Sarah Palin's Yahoo! e-mail account once she joined the 2008 Republican presidential campaign.

Frank Bailey testified he feared the account could and would be hacked.

Bailey testified he set up the account at Sarah Palin's request.

"She wanted to keep her personal and partisan business separate from her state business," he said.

Sarah Palin and her husband, Todd, are expected to testify this week, perhaps as soon as Thursday, in the U.S. District Court trial.

Bristol Palin's testimony buttressed that today of a longtime Palin friend and one-time employee. Ivey Frye told jurors of vulgar and threatening e-mails she and others received after news hit that Palin's personal e-mail had been illegally accessed.

"I received (e-mails) many a day, violent, sexual, threatening ... throughout the course of the (2008 presidential) campaign," Frye testified.

She said the e-mails, which were sent to everyone on Palin's e-mail contact list, were anonymously sent.

She read from one that said: "You don't know me. Neither do I know you, but we can change that."

Recipients of the e-mails included Palin's parents, she said.

Prosecutors allege the contact list wound up on several Internet web sites after Kernell managed to take control of Palin's account in September 2008 and posted screenshots from it onto the 4chan Internet discussion board.

Testimony has shown that dozens of people perused the account before Palin learned via Frye that the password on the account had been changed.

Frye said she learned of the virtual break-ins from an anonymous 4chan member who used Palin's account to send her an e-mail urging her to tell Palin that others on the board were foraging through the account.

Federal prosecutors allege Kernell, then living in Knoxville, had read a story in The New York Times about the possibility that Palin was funneling gubernatorial business through a private Yahoo! e-mail account to avoid public scrutiny.

The son of longtime Memphis Democrat state Rep. Mike Kernell and a self-described "Obamacrat," Kernell decided to see if he could access the account.

Kernell's trial began Tuesday, and an East Tennessee jury of six women and eight men including two alternates is hearing testimony.

"The evidence will show the defendant hoped to derail the (Republican presidential) campaign," Krotoski said.

Defense attorney Wade Davies countered that Kernell was merely being curious and never believed a prominent political figure like Palin would use a poorly protected Yahoo! account.

"This is a case about a prank, not a crime," Davies said. "The evidence will show he acted out of curiosity."

A Kernell roommate testified Tuesday the young student didn't like Palin's politics but "never wanted to hurt her."

Kernell is charged with four felonies including identity theft and wire fraud.

Among the jurors hearing the proof are a Baptist preacher, a software expert, a farmer, a recent community college graduate, a photography buff, a couple of foster parents and a transplanted "Cheesehead" from Milwaukee, Wis.
